Abstract : The report analyzes the impact of FAA programs on airport capacity over the next ten years. Eight major airports (Atlanta, Chicago O'Hare, Denver, Los Angeles, Miami, New York Kennedy, Philadelphia, and San Francisco) were examined in detail. The study found that these programs will have substantial benefits at the airports surveyed. VFR capacities will increase about 25% over today, and IFR about 50%. A major requirement will be the metering and spacing and wake vortex avoidance systems programs. With these systems in place, IFR capacity will rise from its present level of 75% of VFR capacity to about 90%, thus increasing the ability to maintain sustained all-weather operations. If these improvements are achieved, no airport surveyed will in the long term (1979-82) experience peak hour VFR saturation, and only one airport is projected to experience peak hour IFR saturation.
